Application filed August 11, 1916i, Serial No. 11 L439. Renewed March 25, 1918. Serial No. 224,674.

'1 0 all whom it may concern: 7 Be 1t known that I, CLIFFORD O. POOLE, a

citizen of the United States, residing at Balcom, in the county of Union and State of Illinois, have invented certain new and useful Improvements in Rachet-Nut-Turning Machines, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to new and useful improvements in apparatus for removing and tightening nuts upon bolts, especially designed for removing the nuts upon tires of Wheels when it is desired to remove the tire for repairing purposes.

The invention consists of a simple and efficient apparatus of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompauying drawings, in which:-

Figure 1 is a side elevation of my improved apparatus.

Fig. 2 is a vertical sectional view of the invention.

Fig. 3 is a sectional view on line 38 of Fig. 2.

Reference now being had to the details of the drawings by letter, A designates the framework of the machine which has two laterally extending arms, designated respectively by letters B and C, and which is adapted to be held stationary. An oscillatin shaft D has its ends journaled in suitable bearings in said arms and has keyed thereto a driving gear E. F designates a bumper mounted upon the oscillating shaft immediately above the gear wheel E. Mounted in the lower arm B of the frame is a socket member H having a stub shaft H journaled in suitable bearings, and I designates a wrench gear which is fixed to said stub shaft and is in mesh with the teeth of the driving gear E, said socket member H being adapted to be so shaped as to receive a nut to be loosened upon the tire or other object.

Said oscillating shaft D is provided with spiral, intersecting grooves K which are arranged right and left thereon and are provided for the purpose of giving the shaft rotary movement through the medium of the mechanism which will be presently descrlbed.

Mounted to have a reciprocating move ment upon the oscillating shaft is a cylindrical ratchet housing N, and P and Q, designate two ratchet nuts, the former being a right hand nut and the other a left hand ratchet nut and each nut has oppositely disposed integral lugs P and Q respectively which are adapted to intersect the spiral grooves at points diametrically opposite. A rock shaft 0 is mounted in suitable bearings upon the casing and has pawls R and S fixed thereto, adapted to engage respectively two reversely arranged ratchet wheels and a reversing bar, designated by letter J, is held to the rock shaft by means of a set screw J and affords means whereby the shaft 0 may be turned in one direction or the other, accordingly as it may be desired to throw one or the other of the pawls into engagement with one or the other on the ratchet nuts.

Pivotally mounted upon a stud R is a lever B having a slot T formed in one side thereof and which is adapted to engage an anti-friction roller T mounted upon the bar T which is carried by the housing and serves as a means for moving the same as the lever is swung upon its pivot R for the purpose of rotating the oscillating shaft in one direction or the other. Suitable ratchet springs X are mounted upon the rock shaft 0 and bear against the ratchets and are adapted to hold the same yielding-1y in different positions. In order to guide the housing as it reciprocates, a suitable guide arm Y is carried thereby and has aforked end Y which engages over the edge of the bar M which is fastened to the frame of the machine.

In operation, the shaft 0 is rocked through the medium of the lever J keyed thereto in one direction or the other, accordingly as it may be desired to throw one or the other of the pawls R or S respectively into engagement with the teeth of the ratchet nut P or Q. In the drawings, the rock shaft is so positioned that the pawl Sis carried thereby will engage the teeth of the ratchet nut Q and which will hold the ratchet nut from rotating in one direction, while the ratchet nut P is free to rotate in either direction. The lug Q, projecting from the bore of the nut Q, engages the spiral groove K and, when the casing carrying the ratchet nuts is raised by the upper swinging move- 111611fi 0ftl16 lever saidratchet ring beingheld from rotation in one direction will cause a rotary movement to be imparted to the shaft D and, through the medium of the intermeshing gears I and E with the socket member H, the latter will be given a corresponding rotary movement. On the reverse downward throw of the lever R a reverse movement will be imparted to the shaft D by the lug upon the ratchet nut moving backward in the same groove but, in the event of it being desired to cause, upon thedownward throw of the lever, a further rotary movement to the shaft D, it may be accomplished by the operator rocking the shaft '0 to throw the pawl R into engagement with the teeth of the ratchet nut P, in which event the ratchet nut Q would turn idly.

What I claim to be new is 1. A nut loosening and tightening apparatus comprising a' frame, a rotary shaft journaled therein, a nut socket, gear connections from said socket to said shaft, the latter being provided with intersecting spiral grooves, a movable casing through which said shaft passes, reversely arranged, rotatable ratchet nuts mounted within said casing, each nut having a lug projecting from the bore thereof and engaging oneof said spiral grooves, a rock shaft mounted upon said casing, pawls fixed to said rocksha'ft and each adapted to engage the teeth upon one of said ratchet nuts, means for rocking he h f alarm p ve ed to th tr m and connected to, said casing, forming means whereby, as the lever is swung upon its pivot, the casing may be raised and lowered.

2. A nut loosening and tightening apparatus comprising a frame, a rotary shaft journaled therein, a nut socket, gear connections" from said socket to said shaft, the latter being, provided with intersecting spiral grooves, a movable casing through which said shaft passes, reversely arranged, rotatable ratchet nuts mounted within said casing, each nut having a lug projecting from "the'bo-re thereof and engaging one of said spiral grooves, a rock shaft mounted upon said casing, pawls fixed to saidrock shaft and each adapted to engage the teeth upon one of said ratchetnuts, a bar fixed to said rock shaft, a vertically disposed bar upon the frame, a projection upon said easing having a forked end engaging said bar, serving. to guide the casing as it is'raised and lowered, a handle pivoted to the frame and having a forked portion, and pins projecting from the c forked portion.

In testimony whereof I hereunto afliX my signature in presence of two witnesses. CLIFFORD OTIS POOLE. Witnesses Enw. T. VVoonwoRTrr, W. S. RANEY.
